INHALER Specification of Letters Patent.

Application tiled April A21, 1908. Serial No. 428,351.

To all whom. yit may conte/'11:

Be it' known that I, IIAAHLTON WEIN, a citizen of the United States, and resident of the city of Portland, in the eounty of Multnomah and State of Oregon, have invented a newand Improved lnhalei', ot' which the following is a full, clear, and exact description.

My invention relates to inhalers for medicinal use, the several ebjec s of my in'iprovements being as follows: I. 'lo construct the m or other nonciiirrosive material. vIl. To connect the vai'ious parts without soldering, welding or ceinenting. III. To'enable the parts to be cheaply cnisructed by stamping, shearing, spinning and analogous processes, whereby 'the clicapness of production is reduced to a minimum. lV. To give certain metallic parts sut'hloim as to enable them to hold sccurely in position the p'adsused for the iiltiaf tion of an' or tor containing i'nedicines to be inhaled. ',logivethe devicesiit-.l-i asliape as will render it easy of application tothe nostrils and will yn'otecttlhe latter t'i'oininjury thereby. YI. To secure the the truncatedcones in an vvapproved `manner andto give the spring such form as will in'- crease its general efficiency.

'Reference is to he had to theaccompanying drawings forming a partoi this specification, in which similar characters of reference indirate corresponding parts in allthe views.

Figure 1 isa perspective showing the inlialeras used inpractiee Fig. 2 shows the device complete, oonsisting'ol" 'two truncated '1L-.ones each iitted internally with a pad, the concs being connected by :a U.spiing 'secured thereto as hereinafter described; and

Fig. 3 is a vertical section through the meeh- ,anism shown in Fie 9 with the exception that in Fig. 3 one of the pads has been removed. c

Two truncated cones 5 made of aluminum or non-corrosive alloy made by cu ping the edge otv the cone slightly inward an further provided with a smaller opening 7. The edges may be out by spinning, stamping or punching as desired.

A strip 8, integrall with the cone 5, is partially severed therefrom by shearing and is then unehed inwardly as indicated in Fig. 3, thus saving upon each cone 5, a strip 9. A bow spring 1,0, made'also of aluminum or spring to very thin and` light, are each provided with a large openi1ig.6,.

.therein a similar indentation, 12.

non-corrosive alloy, is substantiallyv of U- shape and its ends are inserted respectively within the twoccnes and pressed outwardly against the same by the strips S, the spring thus being in a sense clamped by the strip 8 and'tthc strip t), as will be understood from Fig. 3. The-ends ol' t he spring 1t) are further secured by mal-:ing an indentation 11 in the ends ofthe spring, t hose indcntations slightly atl'ecting the shape of the strip S and raising This eliables the strip 8 to grip iirinly the end of the U-springis used for retaining mcdicin(I organic mattei' discharged trom the `nose or :pieces of proper size and shape.

-l/Vith tic apparatus iliade as abov-ede-` scribed, the truncated cones may beV de? tached from the U-spring, but areziiot-sov easily detached, as to 'readily separatethere lfrom except when such separation is desired..` intents and purposes the parts act ni 'To all' practice as if they were integral with each other. It, however, fa :part be broken, bent or worn out, itfmay be readily replaced by a similar part.

Having thus described my invention, whatv I claim vas new and desire to secure by Letters Patent is:

1. An inlialer comprising a pair of truncated cones, each having its ends open and cupped slightly inward, each cone being provided with slits ,forming a strip partially severed therefrom, and a U-spi'iiig inserted between said strip and the body portion of said cone and clamped therebetweenj 2. An inlialei' comprising a pair of cones of metal, each provided with oppositcly 'arranged and spaced slits forming a strip integral-therewith and partially severed there-` from, said strip being held by its ends only to the cone, and a Usliaped spring having a portion inserted intermediate said strip and thel body portion of said conc for the purpose ofsupporting said cone.

3. An inhaler comprising a pair of cones ot'. metal, each therewith and partially severed therefrom,

yone of said strips being pressed inwardly in provided. with two strips integral A pad 13, of absorbent material is 4 mounted in each of the truncated cones, andv ory absorbing y.

relation to the other of seid strips, and e, U- ing said strip and provided with an indente- .shatped member eonneeting seid cones totion mating said indentation oi' seid strip. gether, said U-shttped member having e porln testimony whereof l have signed my tion inserted intermediate said'strips of each neme to this specification in the presence of 5 @enel h l l h b. f I 1 two subscribingjr witnesses.
